Improvement in heating and other furnaces

, The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that we, THOMAS Hvnns and J osnnH BENNETT, both of Sheffield, in the county of York, England, have invented improved means or applianees for facilitating the Transit and Application of Calorie; also for mixing caloricwithfair, water, and other liuids and gases; also for economizing the consumption of fuel, consuming smoke, generating steam, and increasing and distributing heat; and we do hereby declare that thevfollowing is full and exact description thereof, reference' being had to the accompany-` ing drawing and to the letters of reference marked thereon.

To enable others skilled 'inthe art to make and use our invention, we will proceed toilescrihe its construction and operation.

This invention consists- First, in the application of guides 'or channels to direct hot gases or tluids to the surface of their containers, such as flues, tubes, or other channels, for the purpose of more fully developing and absorbing the caloric iiom the gases oriluids, and using the same for any specied purpose, which caloric would otherwise be lost by passing away through the body or central part of the flues or tubes.

Secondly, inv applying on each, or only on one side of a partition, situated between hot and cold, guides or channels,,through which air, tiuids, or gases are guided in parallel lines, .or nearly so, or in cross-lines, and in constantly-circulating streams which pass nearly instantaneously within the most eifective distance over and entirely cover the whole surface ot" the said partition intended to be acted upon, for the purpose of transferring their heat or caloric from one iiuid to anyv other Huid.

' ""The `following is an example ofthe means by which the above objects may be accomplished.

We propose to construct an upright iiue or duct, of metal or other suitable material, communicating with the flue of a furnace, and one part of said iiue or duct we form inclosed, and against the outer surface of one side or portion thereof, according to the shape of the said tine or duct, we attach guides or channels, of any desired shape, with openings therein, for directing the air against such said suriace.

We also tix guides in the inclosed part of such said flue or duct, the said guides being formed with horizontal partitions across them for arresting thc direct passage ofthe heated air, fluids, or gases over and through them, and thereby causing them to pass under the edges of the said guides, and pass thence against the surface of the cooled partition of the iiue or duet, and through and between the other halt` of the guides, situated at the other sides of their respective horizont-al partition, and so on through each/set of guides, there being several sets fixed in the closed flue or duct.

The heat thus collected on the-.cooled side of the partition may be directed as required, and thon utilized, instead of being dissipated and lost.

'lo apply the above system to hot-air stoves, we proceed as follows:

We arrange the sets of guides both in the pipe or flue ofthe stove and around the outside thereof.

Description of the Drawing. Figure 1, sheet 1, represents a, sectional side ehvation of an arrangement illustrative of the principle of construction our said invention.

Figure 2 is an edge view of iig. 1.

Figures 3, 4, 5, 6, 7 respectively represent perspective and geometrical views of our improvenients, applicable to tubes or pipes. l

Figure 8 is a top plan view of our improvements when applied to a Cornish boiler, the position of the boiler being denoted by dotted lines.

Figure 9 is a transverse and vertical section through the line A l, at tig. 8.

Figures 10 and 11 are similar sections through the lines GD and E F, at iig. 8.

Figure 12 is a longitudinal and vertical section through the line G H, at iig. 8.

. As regards Iigs. 1 and 2, A A are guide-plates, of metal or earthenware, shown detached at Figure 13.

1S is a flat surface or rectangular-shaped chamber, with .a partition, C, therein.

E is space between the partition G and the plates A A, which plates, when arranged as represented by the drawing, operate in the following manner;

Suppose `the said plates to be applied beneath a Cornish boiler, for example, as at fig. 8, and .the heated air, smoke, and gases to enter at A, Athey would take the course denoted by the arrows flight at this figure, that is to say, the heated air, smoke, and gases would pass up every alternate space formed by theguide-plates, antLbe split or divided, and combine when they reached the top edges of the said plates, or those parts marked a a at figs. 9, ,10, 11, where space is left between the boiler' and the-top edges of suc-h said guides. 'lhe heat will thus be brought into contact with the bottom of the boiler, the smoke and waste heat, and gases passing oii along the iiues G, taking the course denoted by the arrows iiight, and iinally passing into the chimney.

And we would here remark, the shape of the guideplates and-mode of arranging them will vary according to the situation in which they are to be used, and

the shape vot the boiler or other vessel or surface to ,which they are to be applied.

. '.Figure 14 shows a detached view of two of the said guide-plates above referred to, as applied to a Cornish boiler.

2. In applying on caclror only on one side of' a partition, situated between hot Vand cold, guides or channels, through which air, fluids, or gases are guided constantly circulating streams which pass nearly instantaneously within the most effective distance over and entirely cover the whole surface of the said partition intended to be acted upon, for the purpose of transferring their heat or caloric from one liuid to any other linid. l
